Sadly, you can't download music from Spotify and Spotify will not allow my app to just play the songs in your Spotify account.

I have written everything to support Spotify in my app, but Spotify has not yet granted me commercial approval. I have requested that approval multiple times over the past three years and they simply don't respond. I suspect I'm just not a big enough app for them to bother with Feel free to contact Spotify and ask them why they won't let you use your Spotify with my Walkout Songs app... if enough users do that, perhaps they will finally talk to me.
